Letters Patent No. 114,919, dated May 16, 1871.

IMPROVEMENT m WHEELS For; TEMPERING cLAv.

The Schedule referred to in these Letters Patent and making part of the same.

and do hereby declare that the following is a full, clear,.

and exact description thereof, reference being had to the accompanying drawing and to the letters of ref- "erence marked thereon making a part of this specifi- The nature of my invention consists in the construction and arrangement of'a wheel or machine for gempering clay, as will be'hereinafiier more fully set orthi 1 In order to enable others skilled in the art to which my invention appertains tov make and use the same, I will nowproceed to describeits construction and operation, referring to the annexed drawing, in which- Figure 1 is a side elevation of my machine, the wheel itself being in vertical section;

Figure 2 is a plan view of the machine; Figure 3 is an enlarged plan view; and- Figure 4, an enlarged side view of a triangular pinion which operates the endless chain to move the wheel in and out.

A represents a block or standard of suitable height, to be attached in the center of the circular tub or ves s el in which the clay is to be tempered. From the center of this block A rises a bolt, a, provided with a stationary pinion, b, and above the same on the bolt is placed the beam B, to the other or outer endof which the horse is attached to go around with said beam in the same manner as the usual sweep for horse-powers.

At a suitable point through the beam B is passed a bolt having upon its lower end a cog-wheel, O, which gears with the stationary pinion b,- and upon its upper end is a double-flanged triangular sheave, D, around which the endless chain dis placed.

The beam B is made square or other suitable shape, and provided on its upper side with a longitudinal rib, j; which is cut and mortised at a suitable point, as shown in fig. 1, for the insertion of a. roller, 6, around which the chain ll passes, and for the passage of a pin, 1', projecting upward from one of the links in the chain.

Upon the beam B and rib f is placed asleeve, G, with a collar, h, at each end, the outer one of these collars being removable, so that the. wheel E may be placed upon the sleeve and held upon thesame by the attachment of said outer collar by set-screws or 1' other convenient means. I

The hole in the sleeve G, through which the beam B passes,-is.made of such size and shape that thesleevc may be allowed to slide out and in on the beam-land over the chain 01.

On-the upper side of the inner collar h is made a' recess, with a pin, m, in the same, and the pins m and t are connected by a rod,- H, placed on said pins, as shown fully in fig. 1. p

' As the beam B swings-around on its pivot a the wheel 0 is slowly rotated by gearing with the pinion 11, thereby also rotating the double-flanged triangular sheave D, which operates the endless chain 11.

The sheave Dis so constructed that its corners will catch on every other link in the chain, and by the movement ofthe chain the wheel E is, of course, drawn in and out on the beam; or, rather, the sleeve .G is

"drawn in and out, carrying the wheel with it, the

wheel at the same time revolvingon the sleeve.

The rib f .on thebeam acts as a guard for the chain d, when the sleevepasses over the same, and at the same time it prevents the wheel from canting to either side, butholds it in the proper position all the time.

The double-flanged triangular sheave D, operating the-chain d to move the wheel back and forth on the beam, in addition'to other advantages; acts with a Inore steady and uniform motion than the rack and pinion heretofore'employed for that-purpose. v

jHaying thus fully described my invention,

What I claim as new, and desire to secure by Let ters Patent, is'- .1. The double-flanged triangular sheave D for operating the endless chain d, substantially as herein set forth.

2. The combination of the double-flanged triangular sheave D, chain (1, roller 0, pins 11m, and rod H,

substantially as and for the purposes herein set forth.

3. The combination of the beam B, rib j, sleeve G with collars h hand wheel E, pins m i, roller 0, chain 11, double-flanged triangular sheave D, cog wheel O, and pinion b, all substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 25th day of .April, 1871.

FRANKLIN L. OARN ELL.
